Webb2 maj 2024 · Density of the solution = Step-by-step explanation: Given that, 6.90 moles of KOH are present in 1 litre of the solution. Molar mass of KOH = We know, ∴ . Thus, volume of solution containing 386.4 g KOH = 1000 mL. Now, 30% by mass of KOH solution means that 30 g of KOH are present in 100 g of the solution. ∴ Mass of solution containing 386. ... WebbSince potassium hydroxide makes up only 30% of the solution, the actual mass of the solution is: mass of solution = 386.4 g / (30/100) = 1,288 g The density of a substance is … WebbRecently completed practical PhD in Artificial Intelligence (Machine Learning - Deep Learning); Published three scientific papers; Invented a students’ performance model, which improved students’ academic performance in two universities; Developed a 3D representation and monitorisation of universities students’ academic problems; Created … shelved armoire
